For many Canadians, summer time means time at the lake, swimming, fishing, boating, and relaxing. Nothing can spoil this experience like blue-green mats of muck, caused by algal blooms. These blooms negatively affect not only recreational activities but also put drinking water source, property values, wildlife, and human health at risk. In the 1970s, scientists discovered that the nutrient phosphorus caused algal blooms, which led to new regulations and improved sewage treatment. Nevertheless, blooms continue to plague many Canadian lakes. To investigate what might be happening, scientists looked to see whether phosphorus might be recirculating from the mud at the bottom of lakes back into the water.

Ian Gates describes each pebble of bitumen as resembling a liquid-filled headache capsule and, for an Alberta struggling to build pipelines, this tiny package could spell pain relief indeed.

Freshly patented and weeks away from pilot-scale production, the professor’s revolutionary heavy oil and bitumen pellets may finally provide a pipeline-free solution to getting Alberta’s largest oil reserves to market in a cheap, sustainable manner, while vastly reducing the environmental risk of transportation.

Se espera que los peces disminuyan en tamaño entre un 20 y un 30 por ciento si la temperatura del océano continúa subiendo debido al cambio climático. Un nuevo estudio realizado por investigadores de la Universidad de Columbia Británica proporciona una explicación más profunda de por qué se espera que los peces disminuyan de tamaño.

Conservation initiatives led by local and indigenous groups can be just as effective as schemes led by government, according to new research.

Backyard chickens are permitted in a number of Canadian cities, including Vancouver, Victoria, Whitehorse and some boroughs of Montréal.

Wanda Martin would like to see Saskatoon on that list.
